SPECIFICATION forming part of Letters Patent No. 793,141, dated June 27, 1905.

Application filed December 7,1903. Serial No. 184,056.

To all whom it may 0011100771,:

Be itknown that I, FRANK E. hIARsHALL, a citizen of the United States, residing at Porterville, Tulare county, State of California, have invented certain new and useful Improvements in Shoe-Polishing Machines; and I do hereby declare the following to be a full, clear, and exact description of the same.

The present invention relates to a certain new and useful apparatus for mechanically polishing shoes, the same comprising aseries of pairs of brushes which act successively to clean the shoe to be polished, apply the black ing or polishing material to the surface thereof, and to polish the shoe, combined with a suitable foot-rest which is so arranged that the shoe held thereon is acted upon by each pair of brushes. Preferably each pair of brushes is located in a different horizontal plane, and the foot-rest at predetermined periods is raised by a step movement into different horizontal planes during the work of polishing a shoe, so as to bring the shoe held thereon into the field of action of the various pairs of brushes.

To comprehend the invention, reference should be had to the accompanying sheets of drawings, wherein Figure 1 is a side view in elevation of the apparatus. Fig. 9. is a plan view of the mechanism disclosed by Fig. 1 of the drawings; and Fig. 3 is a front view in elevation of the apparatus, the position of the respective pairs of brushes being illustrated, also the rotary brush for polishing the top surface of the shoe.

In the drawings, the numeral 1 is used to indicate any suitable style of frame for the apparatus, which is designed to form a portion of any conventional form of a shoe-polishingstand. Within the frame 1 two pairs of spaced vertical shafts 2 2 are arranged, to each of which shafts three drums or rolls 8 4: 5 are secured. Four, or two pairs of vertical shafts and six pairs of drums or rolls are thus provided. Over the drums or rolls work, respectively, the pairs of endless traveling belts 6 7 8, the lower pair of endless belts6 working over the drums or rolls 3, the second pair of belts '7 working over the middle rolls or drums 4, and the third pair of belts 8 working over the upper rolls or drums 5. Thus three pairs of horizontally disposed endless traveling belts are provided, to which belts the brushes 9 10 11 are attached. Of these brushes the lower pair constitute the cleaning-brushes for removing the dirt from the shoe to be polished, the middle pair for applying the blacking to the shoe, and the upper pair for polishing the shoe after the blacking has been applied.

Between the endless traveling brushes is located the foot-rest 12, which rest is raised and lowered by means of the crossed levers 13 let. These levers at opposite ends are pivoted between the ears 1 L 1& depending, respectively, from blocks 14 and 1 1", upon which the heel and toe portions of the said foot-rest are slidabl y mounted. The opposite end of the lever 13 is pivotally secured on the rod-support 13, extending between the outwardlyagrojecting brackets 15 on the frame 1, while the opposite end of the lever 141 is fulcrumed to the bifurcated block 15, upwardly projecting from said frame. The crossed levers 13 let are centrally connected by means of the pin 16 passing through one lever and working within or through a slot 16 in the opposing lever, Fig. 1 of the drawings. By the employment of the crossed levers 13 14 a lazy-tong connection is made between the foot-rest and the supporting-blocks 15 15. The foot-rest is given a step vertical movement to place the same in different horizontal planes by means of a cam 17, secured to a longitudinal shaft 17, working against the under face of the lever 13 during rotation of the said shaft 17. 17 represents oppositely-disposed brackets mounted upon the frame 1, adapted to support the shaft 17. The movement of the cam 17 is so timed that the footrest 12 remains in its lowered position sufiiciently long to enable the pair of endless traveling brushes 9 to remove the dirt from the shoe to be polished, when the cam 17, acting upon the lever 13, raises the foot-rest, so as to place the shoe resting thereon between the pair of endless traveling brushes 10, which brushes apply to the shoe the required blacking or shoe-polishing material. By this time the cam will be so positioned as to impart to the shoe-rest, through its action upon the lever 13, an additional upward movement sufiicient to place the shoe held upon the foot-rest between the pair of endless traveling polishing-brushes 11. The foot-rest is held in such position a predetermined length of time, which, as stated, is sufficient to permit of the shoe being perfectly polished by the pair of rapidly-traveling polishing-brushes 11. While the brushes 11 are polishing the shoe the rotary brush 18 bears upon and polishes the upper surface of the shoe. It is believed that this brush may be dispensed with, inv which case the length of the bristles constituting the pair of brushes 11 will suffice for this purpose; Still it is deemed advisable to provide for such polishing of the shoes upper surface, inasmuch as the polishingbrushes 11 may not answer to polish the sides and top of the shoe. After the shoe has been polished the action of the cam 17 upon the lever 13 is such as to allow the foot-rest to move downward or be restored to its original position. The moment the foot-rest proceeds to move downward the user of the machine is made aware that the shoe has been polished, and thus notified to remove his foot from the said foot-rest. However, the drive mechanism for the apparatus may be so governed as to bring the working parts to a state of rest after the shoe has been polished.

The forward pair 2 of the vertical shafts may be said to constitute the drive-shafts for the pairs of endless traveling belts and brushes, which shafts are driven from the main drive or power shaft 19 by means of the bevelgears 19 thereon, meshing with similar gears 19 secured to the lower end of the vertical shafts 2, Fig. 3 of the drawings. The drive or power shaft 19 is driven by means of any suitable operating mechanism. (Not shown.) To the said shaft 19 is also secured the gear 20, which gear meshes with the gear 20, attached to the lower end of a vertical shaft 21. This shaft at its upper end also car ries a gear 22, which in turn meshes with a gear 22, secured to the longitudinal shaft 23, so that the said shaft 23 is driven from the power-shaft 19. This shaft 23 has secured thereto the drum or roll 23, which drum or roll carries the polishing-brush 18. The shaft 23 works in bearings of the brackets 23 projecting upwardly from the frame 1.

Any suitable means may be employed for supplying to the middle pair of brushes the blacking material to be applied to the shoe.

On the power-shaft 19 is located a Worm 24, which meshes with a worm-wheel 24, secured to a short vertical shaft 24. Thisshaft On the outer end of the said shaft 25 is located a worm 26, which meshes with a worm-wheel 26, secured to one end of the longitudinal shaft'l'i", carrying the operatingcam 17 for the foot-rest. rotation of the power-shaft 19 is transmitted to the shaft 17 to operate the cam 17 so as to actuate the said foot-rest at predetermined moments.

No attempt has been made to illustrate the driving mechanism for the power-shaft, for

any form of mechanism may be'utilized for such purpose. 0

Having thus described the invention, what is claimed as new, and desired to be protected by Letters Patent, is
